Salicyl alcohol is produced by the hydroxymethylationofphenol using formaldehyde:[4]
Air oxidation of salicyl alcohol gives salicylaldehyde.
Chemical sweeteners are formed by acetal formation with e.g. isovanillin (Cmp4).[5]
Salicyl alcohol appears as a pharmacophore in several notable β2-adrenoceptor agonists (e.g. salbutamol), as well as in synthetic estrone analogs, e.g. CID:22940780orCID:154236944.
Salicyl alcohol is the precursorofsalicylic acid.[6] It is formed from salicinbyenzymatic hydrolysis by Salicyl-alcohol beta-D-glucosyltransferase or by acid hydrolysis.
